Mutt/exim - multiple email addresses

[Gary Jones]

What's the best way of rewriting addresses when you have multiple 
email accounts all pointed at the same local login? I've got exim 
setup to rewrite the 'From' on outgoing mail so that [EMAIL PROTECTED] 
becomes one of my real email addresses, which is fine as far as it 
goes. The problem is that I would like to be able to send email from 
my other addresses as well, with the correct 'From'. Some sort of 
interactive script thing, maybe? Does mutt have that kind of 
extensibility, like slrn?
